It's very simple: don't use rollback segments. Set up your UNDO_TABLESPACE and let oracle handle it. If you use oracle managed datafiles, oracle will create as much room as it needs. The parameters that you need to look at are:
DB_CREATE_FILE_DEST DB_CREATE_ONLINE_LOG_DEST_n UNDO_MANAGEMENT UNDO_TABLESPACE UNDO_RETENTION UNDO_SUPPRESS_ERRORS The UNDO_MANAGEMENT=auto setting will make oracle manage it's own rollback structures and you will not see the rollback segments. It is just like the BI file (does anybody still remember VAX/VMS, ORACLE$BI, IOR and ODT?) In particular, that means that you will not have to worry about the rollback segments ever again. -----Original Message----- Sent: Monday, February 18, 2002 10:34 AM To: Multiple recipients of list ORACLE-L Hello DBAs Is there a command that tells me which rollback segment is being used by current transaction? Also, can you force a session to use particular rollback segment? I have used in the past the command: set transaction use rollback segment rbs_01 but the named rollback segment seemed to be used until the end of tranasction. After a commit or rollback a different rollback segment could have been used by Oracle. I wonder if there is a way to make sure that once a user logs in, a particular rollback segment is used.
